Nara Canal
Pakistan
The Nara Canal, which takes off from the Sukkur Barrage and The Nara Canal drains in to Shakoor Lake before overflowing into Kori Creek (also called Koree Creek and Puran River) of the Great Rann of Kutch, is a delta channel of the Indus River in Sindh province, Pakistan that was built as an excavated channel stemming off the left bank of the Indus River to join the course of the old Nara River, a tributary c.q. paleochannel of the Indus which received water from the Ghaggar-Hakra until the Hakra dried-up, early 2nd millennium BCE. This is one of the largest and oldest canals in Pakistan. It takes off from the Sukkur Barrage on the Indus River and follows the ancient bed of the Hakra/Nara River. It provides freshwater to millions of acres of farmland in Khairpur, Sanghar, Mirpurkhas, and Umerkot. After the 1819 Rann of Kutch earthquake created Allah Bund which caused the formation of upstream Shakoor Lake and downstream Sindri Lake, the Left Bank Outfall Drain (LBOD) was constructed to bypass the Allah Bund and discharge directly into the Kori Creek. However, during the massive floods of 1999, 2011, and 2024, the LBOD failed. Instead of reaching the sea, the toxic saline water backed up and spilled into Shakoor Lake and the Nara drainage basins, flooding the very lands it was supposed to protect. Because the LBOD often fails to reach the Kori Creek efficiently, it dumps saline
